Appears in: Star Wars: The Clone Wars
The best duel in The Clone Wars series, the lightsaber fight between Maul and Ahsoka, is some of the best Star Wars content you'll ever see.
Ahsoka, leading the Republic forces in taking back Mandalore, fights with Maul, who wants to lure Obi-Wan and Anakin there. While they went to Coruscant to save Palpatine, Ahsoka went to take down Maul.
After Maul divulges that he's seen what Palpatine is planning and that Anakin will fall, Ahsoka refuses to join him. The two then engage in combat, and you can almost immediately tell that this fight is perfectly choreographed, and the motion capture is incredibly sleek and fun to watch.
Ray Park, who played Maul in The Phantom Menace, returned to motion capture him for this fight, and it immediately shows. The fight ends with Maul's capture at the hands of the Republic, as he screams for them to let him die to avoid what is come.
It's an incredibly chilling moment and one that sticks with you for a while.
